The wait was worth it — the footage from the Lego man’s impressive journey turned out and the two teens posted it to YouTube.

According to CityNews, the project cost the teens – who are Grade 12 students at Toronto’s Agincourt Collegiate Institute – approximately $400.

The two friends estimate the unit climbed to approximately 80,000 feet before the balloon popped.

“It shows a tremendous degree of resourcefulness,” Dr. Michael Reid, a University of Toronto astrophysics professor, told the Star. “For two 17 year olds to accomplish this on their own is pretty impressive.”
